The present work aims to make use of "solution" or "dispersion" strengthening of metallic materials by molecules or nanocrystalline C60.Crystalline C60 (20 vol.%) and copper powders were sealed under nitrogen atmosphere and milled in a zirconia pot with balls of the same material 10mm in diameter. X-ray diffraction data indicate that C60 crystals disappear and the lattice spacing of copper increasses by MA.A transmission electron microscopy (TEM) shows that C60 changes into graphite or amorphous diamond-like phase.The milling was made by balls 3mm in diameter and the powders were compacted into disc 10mm in diameter and 1mm in height under 370Mpa. The discs were annealed between 100ﾟC and 700ﾟC.The C60 phase is in this case observed by TEM after 128h MA.The copper discs with 5vol.% as wells as 20vol.% C60 show Vickers hardness of about 200 after annealing at 600ﾟC.In the case of milling of aluminum with C60, the compaction by the same method was unsuccessful.The results indicate that metal-fullerene alloys can be made by selecting metals and milling conditions.

目前的工作旨在利用分子或纳米晶体C60加强金属材料的“溶液”或“分散”。CrystallineC60（20卷％），铜粉在氮气中密封在氮气中，并在齐罗尼亚锅中铣削，并在同一材料的含量10毫米的小球中磨碎。 X射线衍射数据表明C60晶体消失了，MA透射电子显微镜（TEM）增加了铜的晶格间距，表明C60变为石墨或类似无形的钻石相位。通过直径3mm进行磨粉，直径为3mm，将粉末压缩到直径为10mm的圆盘中，直径为10mm，在较低的少于1mm和1mm中。将光盘退火在100 c至700°C之间。在这种情况下，TEM在128h ma之后观察到C60阶段。铜盘的铜盘，含量为5Vol。％，均为20vol。％C60显示Vickers的硬度约为200，在600 c.在C60的情况下，该方法在600 c. c60的情况下，该方法是由C60的铣削构成的。可以通过选择金属和铣削条件制成金属富集烯合金。
